[Constitution of the invention]

[0006]

Means for Solving the Problems To solve the above-mentioned problems, a technical solution provided by the present invention is a transparent synthetic resin panel composed of a panel portion and a frame portion located at the periphery of the panel portion. In a window provided on both sides of the transparent synthetic resin panel and provided with a film having a hard coat treatment on the surface, the window has an untreated portion on the surface which is not subjected to the hard coat treatment. The untreated portion is a window having a bright portion characterized by being plated to form a bright portion. As a method for realizing the invention of the above structure, a transparent synthetic resin is hard-coated. It comprises a first step of integrally molding with the applied coating film to form a window having an untreated portion of the hard coat, and a second step of plating the untreated portion. There is provided a method for producing a window with a bright portion.

[0007]

When the plating process is performed, the plating does not adhere to the surface that has been subjected to the hard coat process, and only the unprocessed part is plated to form a bright part. Therefore, if a portion that is not subjected to the hard coat treatment is formed in advance, a window having a bright portion can be formed without using other members such as a fixture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to the drawings. In this embodiment, the window of the present invention is applied to a quarter window of an automobile. FIG. 1 shows a front view of the quarter window 1. As described above, the quarter window 1 includes the transparent portion 2 and the opaque portion 3 around the transparent portion 2.
And a bright portion 4 located further on the periphery than the opaque portion 3. The opaque portion 3 is for the purpose of improving the appearance of the product and hiding the jig for fixing to the vehicle body, and the bright portion 4 is plated for the purpose of improving the appearance of the product.

Next, a method for manufacturing the quarter window 1 will be described. First, a method for manufacturing the films 6 and 6'disposed on the outer surface and the inner surface of the quarter window 1 will be described. Film 6 disposed on the outer surface
Regarding (FIG. 2), first, one side of a 0.5 mm-thick polycarbonate film was subjected to a siloxane-based hard coat treatment, and the hard-coated treatment was used as the outer surface, and from the shape of the quarter window 1. Punching is performed so that the shape is the same as the shape excluding the portion where the bright portion is formed. The film thus punched has a smaller area than the quarter window 1. Next, an opaque printing layer 10 (FIG. 3) was printed on the film by screen printing using an acrylic paint on the peripheral edge of the surface of the punched film that had not been hard-coated.

The film 6 '(FIG. 2) arranged on the inner surface of the quarter window has a thickness of 0.5 m.
One side of the polycarbonate film of m is subjected to a UV-curable acrylic hard coat treatment, and punched into a shape substantially the same as the opposite side of the quarter window 1.
Then, an opaque print layer 10 '(FIG. 3) was printed on the peripheral portion of the film opposite to the hard coat-treated surface by screen printing using an acrylic paint.

Two films 6, 6'made in this way
2 are set in the mold 7 shown in FIG. 2 so that the surface on which the hard coating is applied is the mold side, and then a polycardnate resin is injection-molded between the two films. , The films 6, 6'and the synthetic resin portion 5 are integrally molded. FIG. 3 shows an enlarged view of part A in FIG. As described above, the synthetic resin portion 5 includes the central panel portion 5a and the frame body portion 5b.
The frame body portion 5b is partitioned by the panel portion 5a and the step portion B. The panel portion 5a is a so-called window portion, and the frame body portion 5b is formed over the entire peripheral edge of the panel portion. The film 6 disposed on the outer side surface of the synthetic resin portion 5 includes a hard coat layer 9, a polycarbonate film layer 8 and an opaque printing layer 10.
The opaque print layer 10 is printed only on the portion in contact with the frame portion 5b. Since the film 6 does not cover the entire synthetic resin portion 5, the frame body portion 5 has the exposed surface 11 of the synthetic resin portion 5. The film 6'also includes a hard coat layer 9 ', a polycarbonate film layer 8 and an opaque printing layer 10', and covers almost the entire lower surface of the synthetic resin portion 5. Opaque print layer 10 '
Covers a part of the frame body portion 5b and the panel portion 5a.

After that, the synthetic resin portion 5 having the films 6 and 6'is subjected to chemical plating, electrolytic copper plating, electrical nickel plating, and electrical chromium plating in this order on a polycarbonate resin plating line. Since plating is not attached to the hard coat treated surface, only the exposed surface 11 of the synthetic resin portion 5 is plated to become the bright portion 4, and the quarter window 1 shown in FIG. 1 is manufactured.

Next, a method of manufacturing the quarter window 1 by the method of the second embodiment of the present invention will be described. The manufacturing method of the second embodiment is different from that of the first embodiment in the film manufacturing method. In the second embodiment, first, as the film 6 to be disposed on the outer surface, a polycarbonate film having a thickness of 0.5 mm is punched out into a shape substantially the same as that of the quarter window 1, and a silicon-based hard film is formed while masking a portion to be provided with a bright portion. The coating is applied to one side. In addition, an opaque print layer was printed on the film by screen printing using an acrylic paint on the peripheral portion of the surface not subjected to the hard coat treatment.

Similarly, with respect to the film 6'disposed on the inner surface, a polycarbonate film having a thickness of 0.5 mm is punched out into a shape substantially the same as that of the quarter window 1, and one side is hard-coated and the other side is hard-coated. An opaque print layer was printed on the area. The hard coat treatment of the film 6'was performed on the entire one surface of the film 6 '.

Two films 6, 6'made in this way
Is set in a mold as in the first embodiment, a polycarbonate resin is injection-molded, and the synthetic resin portion 5 is integrally molded together with the films 6 and 6 '. As shown in FIG. 4, the synthetic resin portion 5 made of polycarbonate resin is covered with the films 6 and 6 ′, but since the film 6 has an untreated portion of the hard coat, the exposed surface 12 of the polycarbonate film exists. It is like this. After this,
A plating process was performed in the same manner as in the first example, and the bright portion 4 was formed on the exposed surface 12 by plating to manufacture the quarter window 1.

Although the hard coat treatment is performed after the film is punched in both the first and second embodiments, the same effect can be obtained by punching the film after the hard coat treatment. Also, the opaque printed layer is
It is also possible to print on the same surface as the hard coat treated surface before performing the hard coat treatment. Further, although the opaque print layer was printed in both examples, this step can be omitted because the opaque print layer is provided for improving the appearance.

[0017]

According to the present invention, since the glitter portion can be provided on the window by plating, it is not necessary to separately provide the glitter portion. Therefore, it is possible to manufacture a window having a bright portion at low cost. Further, since the bright portion is only the plated layer, the thickness can be made thinner than that of the bright portion which conventionally requires the mounting portion. Further, since the bright portion can be formed only by plating, the design is not restricted and the shape of the bright portion can be diversified.
